MINE-CAR-DOOR sI-IIELD.

Application filed scpt ember 16, 1928. Serial 110,135,882.

Thepresent invention relates to car door shield particularly designed for those cars which are used in mines. The purpose of the invention is to prevent the car doors from being broken by rough usage in the mine. Without a shield or other protection, the door of the car is quickly broken and it has to be repaired. Especially is this true of the door rod which holds the door in place. The rod soon begins to sag 1n the center causing the whole door to drop down out of place so that itis hard to open and close the door. The present shield embodying the features of my invention over comes the probability of the door becoming 1njured and secures the long life thereof and allows the car to be used in the same rough way.

An important object of the invention is to provide a shield of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable, reliable and eflicient, and otherwise welladapted for the purpose for which it is designed.

T Jit-h the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novelties of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure l is an elevation of my shield applied to the ordinary mine car door,

Fig. 2 is another elevation thereof taken at right angles to that shown in Fig. 1.

Referring to the drawing in detail it will be seen that the letter A denotes the usual mine car door which is hingedly connected with the rod B by means of brackets C. These parts which I have just indicated generally are well known in the mine car art and do not form a part of my invention except in combination. The mounting of these parts on a mine car is well known in the art and needs no explanation here.

Referring now particularly to my improvement it will be seen that the letter E denotes the corrugated material which forms 7 which pierce the shield and which also pierce the door A and the brackets C thus holding these parts assembled. The numeral 8 denotes an angle iron which is riveted or otherwise fastened as at 9 to the upper edge of the corrugated sheet E and extends upwardly and over the rod 13 and the eyes 10 of the brackets C. 1 As is well known most of the rock broken underground in a mine is used in making the fills in chambers from which the. coal has been taken. Most of the chambers have a grade of from 10 to 80 and when loaded. the cars are sent down the grade with sprags stuck on the wheels. The door latch is used to keep the doors closed and when the door it so that it is hard to operate. The wooden parts of the car are also broken in this manner and are in constant need of repair. The shield is designed by me to be a protection to the car door and especially thecar rod which holds the doors in place and is secured to the side of the door in the well known manner.

It is thought that the construction, utility, and advantages of my invention will now be clearly understood by those skilled in this are without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that changes in the details of construction may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention what I claim as new is 1. In combination, a door, brackets extending vertically of the door and terminating in eyes, a rod projecting through said eyes for supporting said door, a shield on the face of said door, bolts passing through said shield, through said door and through said brackets for holding said shield, door and brackets assembled, and an angle iron fixed to the upper edge of the shield and extending over the rod and the eyes.

2. In combination, a door, brackets extending veltica'liy of the door and terminating in eyes, a rod projecting through said eyes for supporting said door, a shield on the face of said door, bolts passing through said shield, through said door and through 10 said brackets for holding said shield; door and braekets assembled, and an angle iron fixed to .the upper edge of the shield andextending over the rod :and :the eyes, said shield being formed of a corrugated metal sheet haying downwardly and outwardly inclined portions connected by horizontal portions.

3, In combination, a door, brackets extending vertically on the door and terminating; above the upper edge thereof in eyes, a rod projecting through said eyes for sup porting said door, and an angle iron fixed to the upper edge of the door and extending over the rod and over the eyes.

In testimony whereof I afiix my signature.

PATRICK J. LOUGHRAN.
